Thinning Process Sheet Metal

Thinning occurs at the top of the sheet metal.

Thinning process sheet metal.

When these parameters decrease the thinning moves to the bottom fig. At this point you have two measurements. Sheet metal forming process is a major point to st udy in order to ameliorate the final quality of the produced parts. Clinching or press joining is a bulk sheet metal forming process aimed at joining thin metal sheet without additional components using special tools to plastically form an interlock between two or more sheets.

Depth 10 mm a. While the lower end of sheet metal thickness is 0 5 mm it can still be reduced further to form metal foil. In this fr amework several bulge tests have been developed in order to. For sheet metal parts the thickness is the same everywhere.

Thickness of the formed sheet was measured at all the nodes along its length and the minimum was extracted for comparison. Prediction of the deformation zone thickness is an important approach to control the thinning ratio. Thinning helps transform sheet metal to the eventual size needed for use. Sheet metal forming 2 810 d.

Pr 1 mm pr 3 mm. An excessive thickness reducing ratio of the deformation zone in single point incremental forming of the metal sheet process has an important influence on the forming limit. 9 boothroyd dewhurst and knight. Cooper sheet metal forming ch.

N bh 0 2 mm. Sheet metal is metal formed by an industrial process into thin flat pieces. If you have accurate measurements you can have confidence in your results. The starting thickness of your sheet metal call that s and the formed thickness of your part at the location of interest call that f.

Sheet metal fabrication is a cold processing process which is commonly used for punching bending drawing and forming. The percent thinning is calculated as t 100 s f s. Sheet metal usually refers to a thin metal plate with a thickness of 6 mm or less.
